Hi,
Since 1 week i can not connect any website to instagram personal account i get the following message:
Unsupported get request. Object with ID ‘********’ does not exist, cannot be loaded due to missing permissions, or does not support this operation. Please read the Graph API documentation at Graph API - Documentation - Meta for Developers
Greetings and welcome to the Community 
I am terribly sorry for all the frustration caused by the issue!
I see that my colleague Daria has contacted you in a support ticket. As she mentioned, we don’t have a timeframe yet, as this issue happened on Facebook’s side, so it doesn’t only depend on us, unfortunately. But we’re doing everything in our power to resolve this as soon as possible!
Rest assured, Daria will keep you abreast of any changes.
Thank you for your patience and understanding 
Thank you so much i will wait!
